In this case, always ensure that the co-driver's
airbag is disabled.T he PASSENGER AIRBAG
OFF indicator lamp must light up.
If the PASSENGER AIR BAG OFF indicator lamp
remains off and/or the PASSENGER AIR BAG
ON indicator light is lit, do not fit arearward-
facing child restraint system on the co-driver's
seat. Further information can be obtained under
"Problems with the automatic co-driver's front
airbag deactivation system" (Y page 52).G
WARNING
If you secure achild in aforward-facing child
restraint system on the front-passenger seat
and you positio nthe front-passenger seat too
close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG ON indicator lamp is lit
This poses an increased risk of injury or even fatal injury.
Alwaysm ove the front-passenger seat as far
back as possible and fullyr etract the seat
cushio nlength. Alwaysm ake sure that the
shoulder belt strap is correctly routed from
the vehicle belt outlet to the shoulder belt
guideont he child restraint system. The shoul-
der belt strap must be routed forward sand
downwards from the vehicle belt outlet. If
necessary ,adjust the vehicle belt outlet and
the front-passenger seat accordingly .Always
observe the information abouts uitable posi-
tioning of the child restraint system in this
Owner's Manualasw ell as the child restraint
system manufacturer's installation instruc-
tions.
If the automatic co-driver's front airbag deacti-
vation system detects that:
R the co-driver's seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and remains lit. This indicates that the co-driver's
front airbag is disabled.
R the co-driver's seat is occupie dbyachild in a
rearward-facing child restraint system, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the co-driver's front airbag is disabled.
But in the case of achild in arearward-facing
child restraint system, the PASSENGER AIR
BAG ON indicator lamp can be lit continuously
after the system self-test. This indicates that
the co-driver's front airbag is enabled. The
resultoft he classification is dependent on,
among other factors, the child restraint sys-
tem and the child's stature. It is recommen-
ded that you fit the child restraint system to a
suitable rear seat.
R the co-driver's seat is occupie dbyachild in a
forward-facing child restraint system, either
the PASSENGER AIR BAG ON or PASSENGER
AIR BAG OFF indicator lamp lights up after the
system self-test depending on the resultof
the classification and remains lit. The resultof the classification is dependent on, among
other factors, the child restraint system and
the child's stature.
Move the co-driver's seat as far back as pos-
sible. Alwayso bserve the information on
"Child restraint systems on the co-driver's
seat" (Y page 59) and on "Suitable posi-
tioning of the child restraint system"
(Y page 60). Alternatively ,fit the child
restraint system on asuitable rear seat.
R the co-driver's seat is occupie dbyaperson of
smaller stature (e.g. ateenager or small
adult), either the PASSENGER AIR BAG ON or the PASSENGER AIR BAG OFF indicator lamp
lights up and remains lit after the system self- test depending on the resultoft he classifica-
tion.
- If the PASSENGER AIR BAG ON indicator
lamp is lit, move the co-driver's seat as far
back as possible. Alternatively ,aperson of
smaller stature can sit on arear seat.
- If the PASSENGER AIR BAG OFF indicator
lamp is lit, aperson of smaller stature
shouldn ot use the co-driver's seat.
R the co-driver's seat is occupie dbyanadult or
ap erson of astature corresponding to that of
an adult, the PASSENGER AIR BAG ON indi-
cator lamp is lit continuously after the system
self-test. This indicates that the co-driver's
front airbag is enabled. Occupant safety

General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(Y page 197).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached atrailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R parking or stopping restrictions
R in front of driveways or entrances and exits
R unsuitable surfaces Driving systems
